Collaboration frequently yields better results in decision making, learning, and haptic interactions than when these actions are performed individually. However, is collaboration always superior to solo actions, or do its benefits depend on whether collaborating individuals have different or the same roles? To answer this question, we asked human subjects to perform virtual-reality collaborative and individual beam transportation tasks. These tasks were simulated in real-time by coupling the…

Physical Collaboration of Human-Human and Human-Robot Teams
TLDR
The force profile of each partner during the target acquisition task revealed an emergent specialization of roles that could only have been negotiated through a haptic channel, and a "haptic Turing test," replicating human behaviors in a robot partner was attempted.
Let the force be with us: dyads exploit haptic coupling for coordination.
TLDR
Results indicated that dyads produced much more overlapping forces than individuals, especially for tasks with higher coordination requirements, which likely reflects a general coordination principle in haptic joint action, where force amplification allows dyads to perform at the same level as individuals.
On the Role of Physical Interaction on Performance of Object Manipulation by Dyads
TLDR
The physical coordination of two hands during an object-balancing task performed either bimanually by one agent or jointly by two agents is investigated to provide new insights about factors that influence dyadic performance.
Experimental analysis of dominance in haptic collaboration
TLDR
Feedback has an effect as the dominance behavior is even more stable across partners when mutual haptic feedback is provided, and the consistency of dominance behavior across different partners is investigated based on methodologies transferred from social psychology.
Inter-personal motor interaction is facilitated by hand pairing
TLDR
It is demonstrated, for the first time, that pairing of one dominant and one non-dominant hand may promote asymmetrical roles within a dyad during joint physical interactions to enable the agent using the dominant hand to actively maintain effective haptic communication and task performance.

TLDR
This work proposes a method for the determination of two non exclusive roles, an executor and conductor, based on the analysis of haptic data, whereby the signs of force and motion signals are evaluated.
Benefiting from Being Alike: Interindividual Skill Differences Predict Collective Benefit in Joint Object Control
TLDR
The present study shows that previous findings in joint decision-making can be extended to dynamic motor tasks such as joint object control, using a dynamic object control task in which two participants each controlled either the vertical or horizontal movement direction of an object.

TLDR
The effect of haptic interaction in single and dyadic conditions is investigated and an energy-based framework suitable for the analysis of the underlying processes is introduced.
Two is better than one: Physical interactions improve motor performance in humans
TLDR
The motor adaptations during physical interactions to be mutually beneficial such that both the worse and better of the interacting partners improve motor performance during and after interactive practice.
Leaders are made: Learning acquisition of consistent leader-follower relationships depends on implicit haptic interactions
TLDR
For the first time, it is demonstrated the emergence of consistent leader-follower relationships in sensory-motor coordination, and it is shown that haptic interaction is essential for dyadic co-adaptation.
